It's not only the Russians, you should come over here and tune from 4MHz through to 16MHz at night, hordes of Asian voices on SSB and many mystery CW stations that pop up any where at any time, out of Asia.
Who are they? Where are they? What are they talking about? Are they legal stations? Sometimes I think the Russians are the least of our worries, just check out the problems now in the South China Sea.
I was reading an ICAO report on the effect that these Asian radio pirates or whatever are having on HF aviation communications in this region. It's only a matter of when they cause a disaster or accident concerning aircraft.
The article on Russian beacons and markers on CVNI maybe be dated but still informative, glad you like it Jim, I have it saved and put across to Desktop for cross referencing.
